SOLUTION MANUAL FOR AUTOMATION SYSTEM AND COMPUTER INTERGRATED MANUFACTURING SOLUTION MANUAL BY MIKEL P. GROOVER . Ch01 Introduction-3e-SI 12-15, 16/06, 06/04/07 2 Answer: Flexible automation is an extension of programmable automation. A flexible automated system is capable of producing a variety of parts (or products) with virtually no time lost for changeovers from one part style to the next. There is no lost production time while reprogramming the system and altering the physical setup. Accordingly, the system can produce various mixes and schedules of parts or products instead of requiring that they be made in batches. The features of flexible automation are (1) high investment for a custom-engineered system, (2) continuous production of variable mixtures of products, (3) medium production rates, and (4) flexibility to deal with product design variations 1.10 What is computer integrated manufacturing? Answer: As defined in the text, computer-integrated manufacturing (CIM) denotes the pervasive use of computer systems to design the products, plan the production, control the operations, and perform the various information-processing functions needed in a manufacturing firm. True CIM involves integrating all of these functions in one system that operates throughout the enterprise. 1.11 What are some of the reasons why companies automate their operations? Nine reasons are given in the text. Name five. Answer: The reasons give in the text are (1) to increase labor productivity, (2) to reduce labor cost, (3) to mitigate the effects of labor shortages, (4) to reduce or eliminate routine manual and clerical tasks, (5) to improve worker safety, (6) to improve product quality, (7) to reduce manufacturing lead time, (8) to accomplish processes that cannot be done manually, and (9) to avoid the high cost of not automating. 1.12 Identify three situations in which manual labor is preferred over automation. Answer: The five situations listed in the text are the following: (1) The task is technologically too difficult to automate. (2) Short product life cycle. (3) Customized product. (4) To cope with ups and downs in demand. (5) To reduce risk of product failure. 1.13 Human workers will be needed in factory operations, even in the most highly automated operations. The text identifies at least four types of work for which humans will be needed. Name three. Answer: The four types of work identified in the text are (1) equipment maintenance, (2) programming and computer operations, (3) engineering project work, and (4) plant management. 1.14 What is the USA Principle? What does each of the letters stand for? Answer: The USA Principle is a common sense approach to automation and process improvement projects. U means “understand the existing process,” S stands for “simplify the process,” and A stands for “automated
